[PATCH 26/55] scsi: Mark function as static in lpfc/lpfc_bsg.c
Mark function as static in lpfc/lpfc_bsg.c because it is not used
outside this file.
This eliminates the following warning in lpfc/lpfc_bsg.c:
drivers/scsi/lpfc/lpfc_bsg.c:3348:1: warning: no previous prototype for ‘lpfc_bsg_issue_mbox_cmpl’ [-Wmissing-prototypes]

This patch implements the changes requested by Jeremy Linton:
http://marc.info/?l=linux-scsi&m=136242124409687&w=2
The patch revises the command issuing behavior, detecting cases where the
Task Mgmt command may have completed but with a non-successful status, which it
previously treated as a successful TMF. The patch also corrects a flushing of
I/O that was done which should only be done on successful TMF completion.

Enhancements to Debug infrastructure
- debugfs additions for new hardware.
- Correct stack overflow in lpfc_debugfs_dumpHBASlim_data()
- Correct warning on uninitialized reg_val in lpfc_idiag_drbacc_write()
- Separated the iDiag command for capturing mailbox commands for generic
issue mailbox command entry point and for BSG multi-buffer handling.
- Added capturing dumping capabiliy of mailbox command and external buffer
for the completion of the mailbox command so that the outcome can be
examined.
- Changed all the iDiag command structure data array indexing introduced so
far with properly defined macros.
- Added SLI4 device PCI BAR memory mapped register read/browse, write-by-
value, set-bit, and clear-bit methods for both interface type 0 and
interface type 2.

Adapter Interface fixes and changes
- Modify the macro field from lpfc_init_vpi_vpi to lpfc_init_vfi_vpi
- Add the new CQE_CODE_RECEIVE_V1 CQE Code, add code in the driver to handle
the new Code the same as the CQE_CODE_RECEIVE code except that there are
two new checks for this code that will cause the driver to use the new V1
macros for rq_id and fcf_id.
- Fix a bug in lpfc_prep_seq() where the size out of the first CQE was
ONLY being used, even though multiple dmabufs make up the sequence,
each have their own CQE with potentially different sizes.
- Fix bug in lpfc_bsg_ct_unsol_event() where the ulpContext and ulpWord[3]
fields of the XMIT_SEQUENCE64_CX IOCB were being calculated incorrectly.
- Do physical to logical translation before indexing into the active
XRI array.
- Populate physical vpi in the iocb data structure.
- Put the current accumulated total in each IOCB in the chain as we are
walking thru then. The last IOCB in the chain should have the total
length of the sequence.

- Change the check and enforcement of MAILBOX_EXT_SIZE (2048B)
to the check and enforcement of BSG_MBOX_SIZE - sizeof(MAILBOX_t) (3840B).
- Instead of waiting for a fixed amount of time after performing firmware
reset, the driver shall wait for the Lancer SLIPORT_STATUS register for the
readiness of the firmware for bring up.
- Add logging to indicate when dynamic parameters are changed.
- Add revision and date to the firmware image format.
- Use revision instead of rev_name to check firmware image version.
- Update temporary offset after memcopy is complete for firmware update.
- Consolidated the use of the macros to get rid of duplicated register
offset definitions.
- Removed the unused second parameter in routine lpfc_bsg_diag_mode_enter()
